The National Hurricane Center is issuing advisories on Hurricane
Sam, located several hundred miles east-northeast of the northern
Leeward Islands, and on recently upgraded Tropical Storm Victor,
located over the eastern tropical Atlantic.
1. Disorganized showers and thunderstorms continue in association with
a trough of low pressure located about 1000 miles southwest of the
Cabo Verde Islands. Some slow development of this system is
possible during the next couple of days while it moves slowly
west-northwestward across the central tropical Atlantic.
Afterwards, environmental conditions are forecast to become less
conducive for development.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 5 days...low...30 percent.
2. Showers and thunderstorms have mostly diminished with an area of low
pressure associated with the remnants of Peter, located several
hundred miles south of the coast of Newfoundland. This low is
becoming poorly defined while moving northeast over cooler waters
and into a region of strong upper-level winds. Further development
is no longer anticipated. Additional information on this
system can be found in High Seas Forecasts issued by the National
Weather Service.
* Formation chance through 48 hours...low...near 0 percent.
